Innovated structure of wheel rim assembly

An innovated structure of anti-piercing and anti-explosion wheel rim for a vehicle tire, having a ring-shaped bracket device fastened to a wheel rim, comprising a specified number of arched bracket units having juts and recesses and shaft holes on a front and back part thereof, the juts and recesses of respective bracket units being joined to each other, the shaft holes corresponding to each other and joined by bolts, provided on the front and tail of the connection being bracket fastening units joined by juts and recesses, with a fastening ring unit fastened to a hook part of a nut, and fastened by bolt to form a ring-shaped bracket device, on the arched surface of the bracket unit and the bracket fastening unit being a fastening surface, serving to accommodate close contact with different shapes of different types of wheels;

• wherein, clamped between the fastening surface of the bracket device and the wheel rim is a pad unit to enhance joining force and absorb shock impact;
• Wherein, the structures of the bracket fastening units and the bracket units are the same, except that one of them has a nut protruded on one side of the shaft hole, the nut having a hook part;
• the other has a fastening ring unit and a pair of ears with insert holes on one joining side;
• Thereby, a vehicle tire is joined with one side of the wheel rim where a pad unit on its inside ring surface, while other side not yet joined has an opening to accommodate a specified number of bracket units and bracket fastening units and joined with bolts, its fastening surface serving for joining and fastening with the wheel rim, with juts and recesses joined to each other on two ends of the bracket units, the shaft holes being aligned to match each other and joined by bolts, a joined head and tail being joined with bracket fastening unit that are joined by juts and recesses, then the fastening ring unit is fastened to a hook part of the nut, and fastened by bolts to form a ring-shaped bracket device, then the tire and the wheel rim are assembled completely to constitute a safe vehicle tire.
